In Plane A means the sensor is in the same plane as the elbow. Out of Plane A means the sensor is perpendicular to the plane of the elbow. If proper lengths of straight run are not available, position the mounting such that 80% of the run is upstream and 20% is downstream. Use straightening vanes to reduce the required straight run length. Row 6 in Table 1 applies to gate, globe, plug, and other throttling valves that are partially opened, as well as control valves. Misalignment 85 Annubar installation allows for a maximum misalignment of 3. Figure 1. Misalignment ±3 ±3 ±3 5

Vertical Orientation The sensor can be installed in any position around the circumference of the pipe, provided the vents are positioned properly for bleeding or venting. Optimal results for liquid or steam are obtained when flow is up. For steam applications, a 90 spacer will be added to provide water legs to ensure the transmitter stays within temperature limits. The maximum temperature for a direct mounted transmitter is 500 F (260 C). Figure 5. Steam Figure 6. Liquid Flow Flow Figure 7. Gas Flow 360 7

8 Flanged 85 Annubar Quick Installation Guide , Rev DB STEP 2: DRILL HOLES INTO PIPE 1. Determine the sensor size based on the probe width (see Table 2). 2. Depressurize and drain the pipe. 3. Select the location to drill the hole.. Determine the diameter of the hole to be drilled according to the specifications in Table 2. Drill the mounting hole into the pipe with a hole saw or drill. DO NOT TORCH CUT THE HOLE. Table 2. Sensor Size / Hole Diameter Chart Sensor Size Sensor Width Hole Diameter in. (1.99 mm) 3 /-in. (19 mm) + 1/32-in (0,8 mm) in. (26.92 mm) /16-in. (1,6 mm) /16-in.

If opposite-side support model is supplied, a second identically sized hole must be drilled opposite the first hole so that the sensor can pass completely through the pipe. (To determine if you have an opposite-side support model, measure the distance from the tip to the first slot or hole. If the distance is greater than 1-in. (25, mm), it is the opposite-side support model.) To drill the second hole, follow these steps: a. Measure the pipe circumference with a pipe tape, soft wire, or string. (For the most accurate measurement the pipe tape needs to be perpendicular to the axis of flow.) b. Divide the measured circumference by two to determine the location of the second hole. c. Re-wrap the pipe tape, soft wire, or string from the center of the first hole. Then, using the number calculated in the preceding step, mark the center of what will become the second hole. d. Using the diameter determined in step 3, drill the hole into the pipe with a hole saw or drill. DO NOT TORCH CUT THE HOLE. 6. Deburr the drilled holes on the inside of the pipe. 8

9 Quick Installation Guide , Rev DB Flanged 85 Annubar STEP 3: ASSEMBLE AND CHECK FIT-UP For accurate measurement, use the following steps to ensure that Ports A and B are equal distances from the inside walls of the pipe. 1. Assemble the 85 to the mounting hardware with the gaskets and bolts. 2. Hand tighten the bolts just enough to hold the position of the sensor centered in the mounting hardware. 3. Measure the distance from the high point of the weldolet to the first sensing hole, port B, then subtract 1 /16-in (1,6 mm).. Measure the distance from the end of the transferred length in step to the last sensing hole, port A. 5. Compare the numbers obtained in steps 3 and. Small discrepancies can be compensated for with the fit-up of the mounting hardware. Large discrepancies may cause installation problems or error. Figure 8.

Place four 1 /-in. (6 mm) tack welds at 90 increments. Check alignment of the mounting both parallel and perpendicular to the axis of flow (see Figure 9). If alignment of the mounting is within tolerances, finish weld per local codes. If alignment is outside of specified tolerance, make adjustments prior to making the finish weld. Figure 9. Alignment ODF Tack Welds 3. If opposite-side support is being used, center the fitting for the opposite side support over the opposite side hole, gap 1 /16-in. (1,6 mm), and place four 1 /-in. (6 mm) tack welds at 90 increments. Insert the sensor into the mounting hardware. Verify that the tip of the sensor is centered in the opposite side fitting and the plug will fit around sensor. Finish weld per local codes. If alignment of the sensor does not allow enough clearance to insert the opposite side plug, make the necessary adjustments prior to making the finish weld.. To avoid serious burns, allow the mounting hardware to cool before continuing. 10

11 Quick Installation Guide , Rev DB Flanged 85 Annubar STEP 5: INSERT THE ANNUBAR 1. Align the flow arrow on the head with the direction of flow. Assemble the bar to the mounting flange using a gasket, bolts, and nuts. 2. Tighten the nuts in a cross pattern to allow even compression of the gasket. 3. If opposite side support is threaded, apply an appropriate thread sealing compound to the support plug threads and tighten until no leakage occurs.. If opposite side support is a socket weld fitting, insert the plug into the sockolet fitting until the parts contact. Retract the plug 1 /16-in. (1,6 mm) remove the Annubar sensor and apply fillet weld per local codes. STEP 6: MOUNT THE TRANSMITTER Transmitter Mounting, Direct Mount Head with Valves It is not necessary to retract the Annubar when direct mounting a transmitter with valves. 1. Place PTFE O-rings into grooves on the Annubar head. 2. Align the high side of the transmitter to the high side of the sensor ( Hi is stamped on the side of the head) and install. 3. Tighten the nuts in a cross pattern to 00 in lb (5 N m). Transmitter Mounting with Remote Mount Head Temperatures in excess of 250 F (121 C) at the sensor module diaphragms will damage the transmitter. Remote mounted transmitters are connected to the sensor by means of impulse piping, which allows process temperatures to decrease to a point where the transmitter is no longer vulnerable. Different impulse piping arrangements are used depending on the process fluid and must be rated for continuous operation at the pipeline design pressure and temperature. A minimum of 1 /2-in. (12 mm) outer diameter stainless steel tubing with a wall thickness of at least in. (0,9 mm) is recommended including and under 600# ANSI (DN50 PN100). Above 600# ANSI (DN50 PN100), stainless steel tubing with 1 /16-in. wall thickness.threaded pipe fittings are not recommended because they create voids where air can become entrapped and create leakage points. 11

12 Flanged 85 Annubar Quick Installation Guide , Rev DB STEP 6 CONTINUED... The following restrictions and recommendations apply to impulse piping location: 1. Impulse piping that runs horizontally must slope at least one inch per foot (83 mm/m). Slope downward (toward the transmitter) for liquid and steam applications Slope upward (toward the transmitter) for gas applications. 2. Outdoor installations for liquid, saturated gas, or steam may require insulation and heat tracing to prevent freezing. 3. An instrument manifold is recommended for all installations. Manifolds allow an operator to equalize the pressures prior to zeroing and isolates the process fluid from the electronics. Figure 10.

Steam or Liquid Service (below 600 F (315 C)) Mount the transmitter below the process piping, adjust 10 to 15 degree above direct vertical down. Route the impulse piping down to the transmitter and fill the system with water through the two cross fittings. Figure 13. Horizontal Steam and Liquid Figure 1. Vertical Steam and Liquid NOTE Ensure the drain legs are long enough to capture the dirt particles and sediment. Top Mounting for Steam Service (required for steam temperatures above 600 F (315 C)) This orientation can be used for steam at any temperature. However, it is required for installations above 600 F (315 C). For remote mount installations the impulse piping should slope up slightly from the instrument connections on the Annubar to the cross fittings allowing condensate to drain back into the pipe. From the cross fittings, the impulse piping should be routed downward to the transmitter and the drain legs. The transmitter should be located below the instrument connections of the Annubar. Depending on the environmental conditions, it may be necessary to insulate the mounting hardware. Figure 15. Horizontal Top Mounting for Steam 1
